Graphite Crucible
MOQ<5TONS
Khoom Description
Graphite crucibles yog dav siv nyob rau hauv smelting ntawm alloy cuab yeej hlau thiab smelting ntawm non-ferrous hlau thiab lawv alloys nyob rau hauv metallurgy, casting, machinery, tshuaj lom neeg kev lag luam thiab lwm yam sectors vim hais tias ntawm cov saum toj no zoo heev zog. Graphite muaj zog corrosion kuj rau acid thiab alkaline daws thiab muaj tshuaj lom neeg ruaj khov zoo heev.
Khoom nta
Cov thermal conductivity zoo heev: Cov khoom siv graphite muaj cov thermal conductivity siab, uas tso cai rau lub crucible hloov cov cua sov kom sai thiab sib npaug, yog li txhim kho cov cua sov ua haujlwm thiab cov txheej txheem sib xws.
Qhov kub thiab txias tsis kam: Cov crucibles no tuaj yeem tiv taus qhov kub thiab txias thiab feem ntau tuaj yeem siv rau hauv ib puag ncig siab tshaj 2000 degree. Qhov no ua rau nws zoo heev rau kev kub kub smelting thiab hlau ua cov txheej txheem.
Thermal shock resistance: Nws muaj zog tawg tsis kam mus rau qhov kub thiab txias hloov sai thiab tsis yooj yim tawg los ntawm thermal shock, yog li ncua lawv lub neej kev pab cuam.
Chemical stability: Graphite cov ntaub ntawv muaj cov tshuaj zoo stability ntawm qhov kub thiab txias thiab tsis yooj yim rau reacts nrog molten hlau thiab lwm yam chemicals, txo cov pa phem thiab cov khoom poob.
Tsawg expansion coefficient: Lub graphite crucible muaj cov thermal expansion coefficient tsawg, uas txhais tau hais tias nws muaj qhov me me hloov pauv thaum cua sov thiab txias thiab tsis yooj yim rau deform lossis tawg.
Lubricity: Graphite muaj qhov zoo ntawm nws tus kheej lubricating zog, uas pab txo kev sib txhuam ntawm cov hlau molten thiab cov phab ntsa crucible thiab txo cov khoom hnav.
Lub zog siab thiab compression tsis kam: Txawm hais tias graphite yog cov khoom siv nkig, tom qab kev ua haujlwm thiab kev kho kom zoo, lub crucible tuaj yeem ua tiav cov neeg kho tshuab siab thiab compression tsis kam, thiab tuaj yeem tiv taus qee yam kev poob siab thiab siab.
